This invention relates to a steering gearfor motor vehicles of the kindwherein a wormVV gear is interposed between the steerlngwheel y, and thesteering rod,` and the invention con- 0 sists in rendering the gearyieldingly selffvf locking.

This is effected by mounting the worm' resents a section of thewormwheel taken on the line I-I of Fig. 2 and v F Fig. 2 is a section on theline II--II of ig. 1. -A worm wheel a which is geared to the steeringwheel by means of a worm in the usual manner,V is mounted rotatably onits shaft b, the latter being connected by means of a lever to thesteering rod. Rigidly secured to the shaft b is a collar h which isprovided with two diametrically opposite, radial arms The collar andarms aresituated within a recess c in a lateral extension of the wheela, and each arm is located between. two co-axial studs f which formabutments whereby the motion of the wheel can be transmitted to theshaft 7). The studs f are, fr mounted on plates (l which are placedagainst v the shoulders formed by the recess. There is free play betweenthe arms z' and the studs f, and the relative movement' thus allowedbetween thewheel and the shaft is controlled bv strong springs g whichare threaded on. the studs f. Thus while the thrust is normally taken bythe springs `g which absorb the shocks, the studs f positively preventthe road Wheels from reacting on the steering wheel so as to turn thelatter.

I claim: Y i

1\. A steering gearV for motor vehicles of the character described,comprising a worm wheel having diametrically opposed, lateral, segmentalextensions, a shaft whereon said wheel is rotatably mounted, a collarsecured shaft, and springs mounted on the vstuds an taking the thrustofthe arms.

2. A structure as' claimed in claim l wherei .in the studs are carriedby platesmounted 55 on the extensions.v
